Sourdough - One of the icons of the AK gold rush

49er - You know

Au - Elemental symbol for gold

Pyrite - Fool's gold

Nugget - form in which gold is commonly found

Goldberg was mentioned, but you'd have to rename the         other one
"Osborn" - A law firm which used to advertise a lot, at least here in
Phoenix.  They are at least regional, and I believe they are national.  I'm
pretty sure Osborn died a couple years back.

Klondyke - AK gold rush site

Double Eagle - old US $20 gold coin

Rand(y) - as in Krugerrand, the SA gold coins
